Airtac M5Y Rocker Type Mechanical Valve M5Y21006
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5Y Rocker Type Mechanical Valve M5Y21006 is a genuine 5/2-way lever type control valve. A lever that STAYS where it is set - manual restoration, so it holds the circuit. It is an external control, direct-acting valve - the spool is moved mechanically, so there is nothing to wire and no pilot line to plumb. Ports are PT1/8 with a 9.0 mm2 (Cv 0.50) effective area.

Sliding-column (spool) construction, so operating force is not affected by working pressure - there is no back-pressure effect. Lubrication is not required, but once the valve has been run on lubricated air it must stay on lubricated air; AirTAC suggests ISO VG32 or equivalent. The lever type control set is METAL, which gives a longer service life than the engineering-plastic heads. The exhaust outlet sits on top of the body, so a silencer fits directly.
About the M5Y21006
The M5Y21006 is a 5/2-way external control, direct acting valve operated by a hand lever - not by a solenoid coil and not by pilot air. There is no electrical connection anywhere on it, so it belongs to the M5 mechanical family alongside the plunger, roller and button types, not to the 4V solenoid or 4A air pilot ranges. The lever is flipped by hand and the spool switches instantly, giving you a valve you can operate in the dark, in a wet area or in a zone where electrical parts are not permitted. This is the 200-series single control body with a PT1/8 port and an effective area of 9.0 mm2 (Cv 0.50).
Reset behaviour is what sets the Y apart from the spring-return levers: it has MANUAL restoration, meaning the valve stays in whichever position you last set it. Flip the lever and the cylinder extends and holds; flip it back and it retracts and holds. Because the sliding-column spool is not affected by back-pressure, the changeover feels the same at 0.2 MPa as it does at a full 1.0 MPa. The exhaust port sits on top of the body, so a silencer screws straight on without piping around the sides. The Y lever carries a metal control set for long, stable service, and the valve can be body mounted or panel mounted.
Typical applications
Mode selection on a pneumatic press
Fitted at the operator station of a small stamping press, the lever selects between single-stroke and continuous-cycle circuits. Because the Y stays where it is set, the press keeps its selected mode across shifts without anyone re-entering a setting.
Holding a jig clamp during tool change
On a drill jig or welding fixture, flip the lever to clamp the workpiece, then walk away and change tools with both hands free. The manual restoration keeps the clamping line pressurised indefinitely - there is no spring to creep back mid-job.
Isolating a packaging line section
During changeover on a form-fill-seal machine, the lever holds the downstream circuit vented so maintenance can work on the infeed conveyor. The top-mounted exhaust takes a silencer directly, keeping the idle section quiet on the shop floor.
How to choose
If you are torn between the M5Y and the M5D short-handle lever, the difference is the reset: the D springs back to its start position the moment you let go, while the Y stays put, so pick the Y whenever the machine must remember a state - fixture clamped, circuit isolated, mode selected - without an operator standing there holding it. Against the M5HS selector switch the choice is ergonomic: the HS turns and stays, the Y flicks like a gearbox lever, which is faster for frequent mode changes. Body-wise, the 210 series gives you 9.0 mm2 (Cv 0.50) on the 1/8-inch port or 12.0 mm2 (Cv 0.67) if you step up to the 08 port code; the 110 body drops to 8.0 mm2 (Cv 0.45). Size the port to the cylinder, not to the supply line. One warning that applies to every actuator in this family: AirTAC publishes reversal stroke limits per model, and driving the actuator past them damages the valve - check the published lever travel figures in the datasheet before you fix the operating geometry, and never strike the Y lever with a tool to speed up a cycle.
Frequently asked questions
It is a 5/2-way external control, direct acting valve with a hand lever and manual (holding) restoration. Operating pressure is 0-1.0 MPa (0-145 psi) with a proof pressure of 1.5 MPa (215 psi), and the working temperature range is -20 to +70 C. The port is PT1/8 and the effective area is 9.0 mm2 (Cv 0.50). The body is aluminium alloy, running on air filtered by a 40 um element, and lubrication is not required - though if you start with ISO VG32 lubricated air, stay with it.
No. The mini M5 family (with its 2.5 mm2, Cv 0.14 orifice) is built only in three actuator versions: M5B05 plunger, M5R05 roller and M5L05 one-way roller. There is no M5Y05, so if you need a holding lever action in the small body, the common-type M5Y in the 110 or 210 series is the smallest option AirTAC makes. Control sets are available as spares for the common-type bodies, which keeps a worn lever repairable rather than replacing the whole valve.
